.Engines, of which the following is a specification.

Our invention relates to cabureters for explosive-engines; and it has for itsobject to provide means for maintaining the desired relative proportions of air and gasolene vapors irrespective of the load or speed.

Other objects are to provide an auxiliary throttling-valve to be actuated for low and high speeds only, to provide detachable controlling means for automatically regulating invention, taken through the gasolene and the carbureting chambers.

The refereneemumeral 1 designates the carbureter considered as a whole, consisting of a gasolene-chamber 2 and a carburetingchamber 3. The gasolene-cha'mber is provided with an inlet 4 at its lower end, through Which flows the gasolene or other suitable liquid hydrocarbon to be used. The flow of b a valve 5, having a valve-stem 6, extendinghip certain new and useful Im '1 through the. gasolene-chamber and into a central guide-bore 7, formed in a cover 8, screwed into the u per end of said chamber. A float 9 is secured to the valve-stem in any suitable manner and serves to open and close the valve to maintain the gasolene at the re.- quired level in the gasolene-chamber irrespective of the conditions to which the device may be subjected. The carbureterchamber 3 is formed of three separable secupper endsection 11, and tion 12-and by means of sections the several parts of the device are rendered accessible for cleaning or repairs. The intermediate section 10 is formed integrally with the gasolene-chamber and is open at its ends, the lower end being inclined for a purpose to be hereinafter described and having the lower section 12 secured thereto, which latter is in the form of an elbow provided with a corresponding inclined end. The intermediate and lower end sections serve as the vaporizing chamber 15, and for convenient connection said sections are provided with opposite lugs 16 at their meeting inclined ends, through which securing-bolts 17 are passed. To the outer end of the lower section an air-pipe 18 is connected, which ma *lead to any suitable source of obtaining heated air. The upper end section 11 ofthe carbureter-chamber is seated against the upper end of the intermediate section 10 and is secured thereto by means of bolts 19, which are passed through lugs 20, extending laterally from both said sections. Saidupper section is provided at its lower end with a conical extension or wall 21,- providing a valve-seat 22 for a conical air or a lower end seethese separable extension or wall. Said'conical wall serves to divide the carbureter-chamber into two parts, viz: a mixing-chamber 24 and the vanorizing-chamber 15,refe rred to above. The air or mixing valve is provided with a tubular stem 25, which extends up through the removable top or cover 26 of the carbureterchamber and has secured to its upper projecting end a throttling-lever 27, which may be connected with suitable rods to an operating-- handle located at a suitable point to permit of easily operating the valve or to the governor l on the engine. Said valve is held against its tionsviz., an intermediate section 10, an

mixing valve 23, fitting within said conical seat by a spiral spring 28, bearing with one end against the removable cover of the casing and with its other end against the lower inclined arms 29, connecting the valve-body with the hollow stem thereon. If desired,

however, the spring 28 may be dispensed with and in lieuthereofa collar applied to or formed on the valvestem directly beneath I the cover and incontact therewith.

The conical wall 21 is provided with opposite ports or openings 30, which are gradually tapered toward their lower ends and with a central opening 31 at its lower end, into which fits the cylindrical end 32 of the valve 23. Extending from one of the side edges of the ports are radial wings 21", which are located at diametrically opposite points and have their outer edges in contact with the walls of the chamber. The air or mixing valve 23 is provided with corresponding openings 33, which may on turning said valvebe brought to register with the ports in the conical wall 21, or said-valve maybe turned to partly or entirely close said ports.

,Conneeting the gasolene-c'hamber with the vaporizing-chamber is an elbow-conduit 34,

' valve 37 coacts to regulate the supply of gas threaded engagement with the latter at the through said conduit. Said needle-valve extends up through the thbe 35 andis held in upper end thereof, whereby on turning said valve the space between the taperedvalveseat and the tapered end of the valve is diminished or enlarged, depending on the direction in which the valve is turned. i The elbow-conduit is provided with lateral enlargements 38, in which are formed upwardlyand outwardly directed gasol'ene-passages 39 and arranged in line with said passages are gasolene or vaporizing nozzles 40,

which are screwed into said extensions, the.

outer ends of said. nozzles being a trifle above the level of the gasolene in the gasolene-cham- 'ber. By this arrangement the float main tains a constant level in the vaporizing-nozzlles, at the ends of which vaporization takes ace.

I The vaporizing-tubes are inclined to lie parallel or approximately parallel with the .conical wall dividing the vaporizing-chamber fl'onFthe mixing-chamber and in line with and in closeproximity to the unwinged edges of the openings in said wall, the exactlocation of the tube in the embodiment shown being therefore central between the wings on said wall.

The upper end of the gasolene needle-valve 37 is provided with a knurled enlargement or head 41 and has applied to the threaded portion thereof a'clam-ping nut 42, by means of which an angular lock-bar 43 may be clamped to the needlevalve, said lock-bar having its outer end. adapted to enter an opening in the throttling-lever and serving to impart movemern from the latter to the needlevalve, therefore providing *for the actuation of the gasolenc-valve on actuating the air or mixing valve to maintain the proper relative proportions of air and gasolcne vapor, to produce at all times the quickest firing of the explosive mixture, to maintain a high efficiency for the engine, and to obtain an economical adjustment of gas consumption at both above and below normal speed.

The heated air is drawn into the vaporizing-chamber through the air-pipe 18 by the action of the piston in theengine, drawing through a lateral extension or mixture-outlet 44in the mixing-chamber, said latter being connec ted wit-h the explosion-chamber of the engine by means of said mixture-outlet. As the air is drawn up into the vaporizing-cham-' her part thereof passes directly over the vaporizing-nozzles and through the opposite ports in the conical wall and through the opposite openings in the air or' mixing valve, while the remainder comes in contact with the conical wall between the wings and the unwinged edge, of the opposite opening, said wings compelling the air-currents to pass along the conical wall and over the vaporiz ing-nozzles at accelerated speed, thereby as suring perfect vaporization resulting from the disposition and arrangement of parts, whereby all the air is drawn over the vaporizing-nozzles and in passing over the latter has an aspirating effect on the nozzles. The i vaporized air as it is drawn into the mixingehamber through the opposite ports in the conical wall and its, valve meet at the center of the valve, the two opposite currents being thus intimately mixed and a proper'mixture obtained.

We find it of great value in many instances to provide further throttling means than is obtained by the closing of the air-valve, and

this we do by placing within the lateral extension or mixture outlet 44 a butterflyvalve 45, whichis secured'to a rock bar or stem 46, extending throu hsaid' extension, said valve bein normal y full open, but adapted to be c osed to an extent proper tionate to the closing ofthe air-v'alve, which action is obtained'b conneetin the stem 46 of said throttling utterfi y-va ye with the throttling-lever 27 by means of a lever 47 and a link 48. In this manner the size of the mixture-passage leading from the mixing.-

. inflow of the explosive-mixture retarded.

' In somecases it may' not be necessary to increase the flow of. ga'solene to the vaporizing-nozzles in proportion to the increase of air, and when such conditions exist we dispense with the use of thelock-bar 43,-and, after having adjusted the needle-valve, screw the clamping-nut down against the upper end of the guide-tube on. the gasolene-conduit,

which looks the gasoleneevalve in its adjustedi position and permits the"'throttling-lever 27 to move independent.

{, When the engine the velocity of the air-currents is increased and tends to increase the aspirating efi'ect on the nozzles in passing over the ends of the latter,-thereby increasing the proportion of ment. or any the several parts g'asolene-vapor in the explosive mixture. At such times the throttling-lever 27 must be actuated by hand in the manner. hereinbefore referred to or automatically by suitable connection with the governor, so as to partly close the air or mixing valve, at the same time partly closing the throttling butterfly- :valve to restrict the mixture-passage to the engine and retarch'the flow of the explosive mixture thereto. 0

ning at a slow speed, the air-currents must be accelerated, which is done-.by reducing the size of the air-openings in the conical Wall 21 and by restricting the size of the passage leading to the engine, which assures the proper aspirating effect on the gasolene-noz- 2 es.

its angular point with a threaded opening 49, into which a screw is screwed to close the same. By removing said screw the gasoleneconduit can be easily cleaned to remove sedimatter or object that might lodge therein and interfere with the free passage of gasolene therethrough. The angular portion of the gasolene-conduit extends beiow the inclined end of the intermediate section of the carburetenchamber and by reason of said incline 1s rendered'easily accessible on removing the lower end section'12 of the chamber.

Itis to be understood that, although the several -parts of this. device have been described as connected and so serving. to perform a purpose common to all, we do not Wish to limit ourselves to the embodiment of our invention shown, as parts thereof may be omitted and some of the connections between or devices dispensed with without sacrificing any of the advantages or departing from the scope of our invention. 6o
